There are two well-corticated bony fragments distal to the ulnar fovea, adjacent to the ulnar styloid. Most consistent with accessory ossicles.
Case Discussion
Features are most compatible with a bipartite or fragmented os triangulare, an accessory ossicle located between the ulnar styloid, lunate and triquetrum.
